Apple Commission Joins Listeria Outbreak Investigation in Caramel Apples

California Victim Represents the First Wrongful Death Suit in this Listeria Outbreak

 

By Laurie Greene, CalAgToday reporter and editor

On December 19, 2014, the Centers for Disease Control and Prevention (CDC) announced that it is collaborating with several states and the U.S. Food and Drug Administration (FDA) in an investigation of the outbreak of Listeria monocytogenes infection (listeriosis) in commercially produced, prepackaged caramel apples.
The first wrongful death lawsuit was filed in California by James Raymond Frey on behalf of his late wife, Shirlee Jean Frey, 81, against Safeway Inc. over the commercially produced, prepackaged caramel apples, implicated in a 10-state Listeria outbreak responsible for a total of 29 people (as of yesterday) who have been hospitalized, including five deaths.
Though the product in question was linked to Carnival brand and Kitchen Cravings brand caramel apples, specifically, CDC is warning the public not to eat caramel apples–plain or with nuts or other toppings, but clarified, “at this time, no illnesses related to this outbreak have been linked to apples that are not caramel-coated and not prepackaged or to caramel candy.” Safeway removed the product from it shelves.
The investigation is still working to determine specific brands or types of commercially produced, prepackaged caramel apples that may be linked to the illnesses.
Listeria is one of the more deadly food pathogens. The most recent Listeria outbreak occurred three years ago from Colorado-grown contaminated cantaloupes, causing three dozen deaths. The pathogen  affects primarily women, newborns, older adults and other people with compromised immune systems. Symptoms include fever, muscle aches and gastrointestinal problems.
The California Apple Commission is working with other apple producing states and the U.S. Apple Association on this issue.  Should California apple growers receive any calls regarding this issue or need additional information, please contact Alexander Ott, Executive Director the Commission office in Fresno by email at calapple@calapple.org or phone 1-559-225-3000.

NEW TULARE COUNTY ASIAN CITRUS PSYLLID DETECTIONS NEAR EXETER  

BREAKING NEWS 

 

The Tulare County Agricultural Commissioner’s office announced TODAY that one additional Asian Citrus Psyllid (ACP) has been detected on a trap south of the city of Exeter. The latest interception was confirmed by the California Department of Agriculture (CDFA). Maps and current information are available on the Agricultural Commissioner’s website by visiting: http://agcomm.co.tulare.ca.us/default/.

CDFA has already begun to saturate the affected area with detection traps in order to determine the extent of any infestation.The United States Department of Agriculture’s Animal and Plant Health Inspection Service (USDA-APHIS) and CDFA will work collaboratively to determine what steps are taken next.

The Asian citrus psyllid is an invasive species of grave concern because it can carry the disease Huanglongbing (HLB), also known as citrus greening. All citrus and closely related species are susceptible hosts for both the insect and the disease. There is no cure once a tree becomes infected. The diseased tree will decline in health, producing bitter, misshaped fruit until it dies. To date, HLB has been detected on just one residential property in the Hacienda Heights neighborhood of Los Angeles.

“Our staff will continue to support the efforts of our $750 million citrus industry, as well as our residential citrus owners,” said Tulare County Ag Commissioner Marilyn Kinoshita. “I want to emphasize that citrus fruit is safe to eat and the disease is not harmful to human health.”

Residents in the area who think they may have seen the pest are urged to call CDFA’s Pest Hotline at 1-800-491-1899 or the Tulare County Agricultural Commissioner at (559) 684-3350. Media inquiries related to technical questions about Asian Citrus Psyllid and Huanglongbing disease are encouraged to contact Katie Rowland, Account Coordinator for Nuffer, Smith, Tucker Inc. at (661) 817-3638.

Growing Figs for 33 Years at Maywood Farms

Farming Niche Organic Figs with Passion

By: Kyle Buchoff; CalAgToday reporter

Growing up in the Bay Area, Bob Steinacher learned how to harvest and dry apricots on his family’s one-acre plot in the Santa Clara Valley. His family maintained the plot as a hobby, but when houses began replacing orchards there, he decided he didn’t want to leave farming. After graduating from UC Davis, he began farming figs and walnuts full-time in Corning, in Tehama County.

tehama-figs“I’ve had Maywood Farms now for 33 years. My family helped me get started, and we’ve been very successful at what we do.” In addition to growing and harvesting 172 acres of organic figs, Steinacher fresh markets his fruit all over the country. “We have 50 acres of conventional walnuts as well,” he added.

Steinacher’s fig farming operation is unique: “We farm the most northern commercially grown figs in the country as Corning has the same weather as the Fresno area.  We also have to worry about late spring frost and early fall rains, but we can weather that. We have wind machines installed for frost protection.”

Waxing nostalgic about his career, Steinacher reflected, “I have learned a lot over the last 33 years of doing this. I had no background in farming other than a desire to do this. I worked for other orchardists and down at a high school farm when I got out of college. I’ve learned a lot by the seat of my pants.”

“We’ve been very successful,” he continued, “because we’ve found a niche with the organic fresh figs. The fig market has been growing ever since we have been in it, and the organic market—on top of that—is growing very quickly as well.”

BREAKING NEWS: Two New ACPs Found in One Trap Near Exeter

CDFA Has Saturated Exeter Area with Extra ACP Detection Traps

The Tulare County Agricultural Commissioner’s offices announed TODAY that two additional Asian citrus psyllids (ACP) have been detected on one trap south of the city of Exeter. The latest interceptions were confirmed by the California Department of Food and Agriculture (CDFA). Maps and current information are available on the Tulare County Agricultural Commissioner’s website.

CDFA has already begun to saturate the affected areas with detection traps in order to determine the extent of any infestation.The United States Department of Agriculture’s Animal and Plant Health Inspection Service (USDA-APHIS) and CDFA will work collaboratively to determine what steps are taken next.

The ACP is an invasive species of grave concern because it can carry the disease huanglongbing (HLB), also known as citrus greening. All citrus and closely related species are susceptible hosts  for both the insect and the disease. There is no cure once a tree becomes infected. The diseased tree will decline in health,producing bitter, misshaped fruit untilitdies.

Media inquiries related to technical questions about Asian citrus psyllid and Huanglongbing (HLB) disease are encouraged to contact Katie Rowland, Account Coordinator for Nuffer, Smith, Tucker Inc. at (661) 817-3638.

The best way to fight HLB is to suppress the spread of ACPs which can carry it. So, California Citrus Research Board hired Nuffer, Smith, Tucker, (NST) a public relations firm, to raise awareness of ACPs and HLB, especially among the many California homeowners with backyard citrus trees who may unknowingly be harboring the pest, and to encourage the public to take necessary steps to save California citrus.

Research Targeting the ACP Olfactory System Shows Promise

A University of California Riverside Asian citrus psyllid (ACP) research team, led by Anandasankar Ray, associate professor of entomology, has found a new tool that targets the ACP olfactory system.  The ACP olfactory system is sensitive to a variety of odorants (odor molecules) released by citrus plants; in fact the ACP depends on its sense of smell to identify its citrus hosts, and this discovery offers an opportunity to develop new attractants and repellents, according to Ray.

As reported in Entomology Today, Ray’s research has identified a blend of odorants found in nature, including myrcene, ethyl butyrate and p-cymen, that can lure ACPs to sticky traps. In the study, odor-based traps caught nearly 230 percent more ACPs than conventional traps placed on the same trees.  “What’s particularly encouraging is that these three chemicals are affordable, useful in small quantities, and safe for human handling,” said Ray, with the potential of being developed into monitoring, masking and surveillance tools.

“We anticipate that this odor-based insect lure could be of use to growers in California and other parts of the world where ACP invasion is occurring,” Ray commented. “Our study also reports identification of odors that block the ACP olfactory system from detecting citrus odors and have potential for development into repellents.”

“Similar approaches can be taken to develop control strategies using odors for other insect pests of crops as well,” Ray explained.  UCR has great strengths in insect chemosensory research ranging from chemical ecology to olfactory and gustatory neurobiology of behavior. With expertise ranging from very basic science to applied areas, several UCR collaborating laboratories are working to find ways to control insects that transmit diseases like West Nile virus and malaria, in addition to citrus greening disease. UCR discoveries have the potential to bring about a paradigm shift in controlling these diseases. 

Study results on the lures were published in PLOS ONE, and the large-scale identification of odors detected by ACP was published in Chemical Senses.

ACP Quarantine in San Joaquin County, Guidelines and Scholarship

Expanded ACP Quarantine

Two portions of San Joaquin County have been placed under Asian citrus psyllid (ACP) quarantine following detections of one ACP within the City of Manteca and one within the City of Lodi. The quarantine zone in Manteca measures 105 square miles and in Lodi it measures 95 square miles.

The quarantine prohibits the movement of citrus and curry tree nursery stock out of the quarantine area and requires that all citrus fruit be cleaned of leaves and stems prior to moving out of the quarantine area. An exception may be made for nursery stock and budwood grown in USDA-approved structures that are designed to keep ACP and other insects out. Residents with backyard citrus trees in the quarantine area are asked not to transport citrus fruit or leaves, potted citrus trees, or curry leaves from the quarantine area.

The ACP, a tiny (0.125 in. length) mottled brown insect that is about the size of an aphid, is an invasive species of grave concern because it can carry the disease huanglongbing (HLB), also known as citrus greening. All citrus and closely related species such as curry trees are susceptible, and there is no cure. Once infected, a diseased tree will decline in health with yellowing shoots, asymmetrical leaf mottling and abnormally shaped bitter fruit until it dies—typically within three years.  HLB was detected once in California, in 2012, on a residential property in Hacienda Heights, Los Angeles County.  This plant disease does not affect human health.

Residents in the area who think they may have seen ACP or symptoms of HLB on their citrus trees are urged to call CDFA’s Pest Hotline at 1-800-491-1899.  For more information on the ACP and HLB, please visit: www.cdfa.ca.gov/go/acp

ACP Effective Treatments

The University of California Agriculture and Natural Resources’ Integrated Pest Management (IPM) Program  has developed treatment guidelines for citrus growers within the quarantine zones. A general principle when applying insecticides to control ACPs in commercial citrus is that no one insecticide fully controls ACP across all life stages because:

  • All stages are difficult to contact with insecticides; eggs and nymphs are tucked inside new foliage and adults can fly.
  • Some insecticides show better efficacy against one stage over another.
  • Because systemic neonicotinoid insecticides require root activity for uptake, they are best applied during June through September.

The UC IPM Guidelines for Citrus provides a ranked list of insecticides that are effective against the Asian citrus psyllid with the pesticides having the greatest IPM value listed first—the most effective and least harmful to natural enemies, honeybees, and the environment are at the top of the table.

According to Mark Hoddle, UC Riverside (UCR) Director, Center for Invasive Species Research, “The science of biological control, the use of a pest’s natural enemies to suppress its populations to less damaging densities,” shows promise against the ACP with releases over the last three years of Tamarixia radiata–a parasitic wasp from Pakistan–in urban areas of southern California Thus far, this natural ACP enemy helps to control ACP growth in residential areas, but is inadequate for commercial application.

ACP Quarantine Expands in Kern, Santa Clara Counties

By Laurie Greene; Cal Ag Today Editor

 

Following the detection of an Asian citrus psyllid (ACP) south of the City of Bakersfield in Kern County, an additional portion of Kern County has been placed under quarantine for the ACP. Likewise, following the detection of psyllids in the City of San Jose near Kelly Park, the first detection of ACPs in Santa Clara County and the Bay Area, a portion of northwestern Santa Clara County has been placed under ACP quarantine.

The additional Kern County quarantine zone measures 148-square miles in and around the City of Bakersfield, bordering on the north by New Stine Road; on the east by S Vineland Road; on the south by Millux Road; and on the west by Interstate 5.

The Santa Clara County quarantine zone measures 99-square miles, bordered on the north by Alum Rock Park; on the south by Santa Teresa Blvd; on the west by N Monroe Street; and on the east by Joseph D Grant County Park.

The ACP is an invasive species of grave concern because it can carry the disease huanglongbing (HLB), also known as citrus greening.  All citrus and closely related species, such as curry trees, are susceptible hosts for both the insect and the disease.  Once a tree becomes infected, there is no cure; the diseased tree will decline in health and produce bitter, misshaped fruit until it dies.

Though the ACP is a dangerous pest of citrus, the fruit is safe to eat and HLB is not harmful to human health, according to Joe Deviney, Santa Clara County Agricultural Commissioner.

USDA's free "Save Our Citrus" iTunes app

USDA’s free “Save Our Citrus” iTunes app

Residents in the area who think they may have seen ACP or symptoms of HLB on their citrus trees are urged to call CDFA’s Pest Hotline at 1-800-491-1899.  Residents with backyard citrus trees in the quarantine area are asked not to transport citrus fruit or leaves, potted citrus trees, or curry leaves from the quarantine area. For more information on the ACP and HLB, please visit the CDFA website.

Better yet, if your citrus fruit is misshapen or discolored or your citrus tree looks sick, send a photo with the new, free SAVE OUR CITRUS app from the USDA. Residents can easily report symptoms, upload a photo and receive a response back from citrus experts. The app includes information and diagnostic tools for all four leading citrus diseases: citrus greening, citrus canker, citrus black spot and sweet orange scab.

Elsewhere in the state, ACP quarantines are now in place in Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara, Tulare, Ventura, and portions of Fresno, Kern, and San Luis Obispo counties.

The disease itself, HLB, has been detected just once in California, in 2012, on a single residential property in Hacienda Heights, Los Angeles County, and is known to be present in Mexico and in parts of the southern U.S.  Florida first detected the psyllid in 1998 and the disease in 2005, but the two have spread to all 30 citrus-producing counties in the state.  The University of Florida estimates HLB has caused the loss of more than 6,600 lost jobs, $1.3 billion in lost grower revenue and $3.6 billion in lost economic activity.  The HLB disease is also present in Georgia, Louisiana, South Carolina, and Texas, and the ACP pest–but not the disease–detected in Alabama, Arizona, Hawaii, and Mississippi.

Asian Citrus Psyllid Quarantine Covers Tulare County Completely

UPDATE: The Asian citrus psyllid (ACP) Quarantine covers Tulare County, in its entirety, following the detection of two psyllids in the City of Tulare. The first ACP was detected in a trap in a residential neighborhood on September 10, in the City of Tulare.  The second detection was on September 17, also in a residential setting within the City of Tulare.  These detections, when added to previous detections elsewhere in the county, dictate that a county-wide quarantine is the most effective response to contain the pest.  A map is available online at: www.cdfa.ca.gov/plant/go/acp-quarantine 

The quarantine prohibits the movement of host nursery stock out of the quarantine area and requires that all citrus fruit be either cleaned of leaves and stems or treated in a manner to eliminate ACP prior to moving out of the quarantine area.  Residents with backyard citrus trees in the quarantine area are asked to not remove fruit from the quarantine area.

In addition to quarantines in portions of Fresno, Kern, and San Luis Obispo counties, ACP entire-county quarantines remain in place in Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara, and Ventura counties.

The ACP is an invasive species of grave concern because it can carry the disease huanglongbing (HLB), also known as citrus greening.  All citrus and closely related species are susceptible hosts for both the insect and the disease.  There is no cure once a tree becomes infected.  The diseased tree will decline in health until it dies.

HLB has been detected just once in California – in 2012 on a single residential property in Hacienda Heights, Los Angeles County.  HLB is known to be present in Mexico and in parts of the southern U.S.  Florida first detected the psyllid in 1998 and the disease in 2005, and the two have been detected in all 30 citrus-producing counties in that state.  The University of Florida estimates the disease has tallied more than 6,600 lost jobs, $1.3 billion in lost revenue to growers and $3.6 billion in lost economic activity.  The disease is present in Georgia, Louisiana, South Carolina, and Texas.  The states of Alabama, Arizona, Hawaii, and Mississippi have detected the pest but not the disease.

Residents in the area who think they may have seen the Asian citrus psyllid are urged to call CDFA’s Pest Hotline at 1-800-491-1899.  For more information on the Asian citrus psyllid and huanglongbing disease, please visit: www.cdfa.ca.gov/go/acp

Biopesticides Play a Bigger Role in Pest and Disease Control

By Colby Tibbet, California Ag Today Reporter

 

Pam Marrone, founder and CEO of Davis-based Marrone Bio Innovations, says biopesticides, a new frontier of pest control, works better when combined with conventional methods. “In the past, these biological products were standalone—like you see at your land grant colleges,” said Marrone.

“They would test standalone against the best cocktail chemicals. But where you see the best result is when they are incorporated into the mix,” said Marrone. “Likewise, nearly all the time, you see better results when biologicals are incorporated into the program than chemical-only programs, and you can validate that over and over again with on-farm demos,” added Marrone.

Marrone noted that biopesticides are price-competitive with traditional pesticides. “When you compare, dollar-for-dollar, today’s biopesticides are actually very cost-competitive. I think that’s a holdover from the past. There are high-priced and low-priced products—just like chemicals; you have sulfur and copper on the low end and chemical fungicides on the high-end.”

“It’s the same with biologicals. So, in our company, we looked at the full range of competitive products and priced in the middle-of-the-block to be competitive,” said Marrone.

“Historically the penetration has been in high-value fruits, nuts and vegetables,” Marrone said, “because of the issues of resistance, residues and worker re-entry. And that’s where the predominant use of these products remains, but there is now an interest is using them in the large-acre crops as well,” said Marrone.
